He got the cover of Menswear magazine, prestigious jobs for Macy's and Bloomingdale's department stores.

Hanrahan accumulated a book of work that put him in demand in all the world's top fashion markets. He began doing TV commercials, campaigns and print ads around the globe. Working in Tokyo, Milan, Zurich and Paris he worked with the world's super models and appeared as the face of designers and products around the globe.
